IOS Mission and Maturation Phase Proposal – In-Orbit Refuelling Assessment

During this Phase 0 maturation study, ASUK, with the support of Thales Alenia Space (TAS), Nammo, MDA and GMV, performed a programmatic, business and technical assessment of a future low-Earth orbit (LEO) refuelling mission. The mission concept proposes developing and demonstrating core technologies in a preliminary service offering to enable a commercial in-orbit refuelling service. Such a service will swiftly redefine how satellites are designed and operated, launching a dynamic and sustainable in-orbit ecosystem with significant potential.

IOS Mission Proposal and Maturation Phase

In the frame of an In Orbit Servicing Maturation Phase (IOSMP) contract, this maturation study has been realised on the START-€ solution which is proposed to extend the lifetime of geostationary orbit (GEO) communication satellites. The START-€ servicer spacecraft will first demonstrate on a GEO communication satellite its ability to perform the critical operations related to its mission, before proceeding with several commercial life extension missions by capturing and taking the AOCS control of aged client spacecraft.

Visualising injector-coupled combustion instability in lox/H2 flames
A recently completed technology activity (ESA-IPL-PTM-sfe-st-LE-2015-510) attempted to systematically test the capability of numerical tools in predicting injection-coupled combustion instability in lres. This type of instability is caused by the coupling of the acoustic pressure field in the combustion chamber to acoustic resonance modes in the injectors. The results demonstrated unsatisfactory predictive capability due to challenges in accurately capturing key aspects in the modelling, such as the distribution of fluid properties throughout the injector-chamber system.

Preparation of enabling space technologies and building blocks: BBK for Low Power PPU

TAS-B has high heritage on PPU for HET ranging from 1,35 kW up to 4,5 kW. In the frame another project, TAS-B  develops New Space PPU modules to drive thrusters in the same power range, for platforms with 100 V regulated power bus. In the frame of the project “BBK for Low Power PPU”, TAS-B addresses the low range of the New Space market: smaller thrusters for smaller platforms with lower unregulated bus.

Magnetic Powder as Propellant in Electrostatic Thrusters (MPEP)

The main objectives of this project were to develop a thruster prototype based on magnetic powder electrostatic propulsion and to test it in vacuum with direct thrust measurements. The aim was to check the robustness of the concept and to measure and calculate important performance parameters such as thrust and specific impulse, to allow a comparison with other thruster technologies. This project demonstrated for the first time the feasibility of electrostatic propulsion based on powder emission.
